The term dual boiler is used narrowly for machines with two separate boilers, and more broadly for what are more properly called dual heater (DH) machines,[citation needed] featuring a boiler for brewing and a separate thermoblock (TB) for heating brew water to steaming temperature – opposite to HX machines, where the boiler is at steaming temperature and is cooled to brewing temperature.
An evenly tamped shot requires the tamp to fit into its portafilter basket precisely. Each machine comes with its own tamp, so we were surprised to find that not all of them fit. Some were too small, leaving behind a crescent moon of untouched coffee. It’s possible to try and compress in sections, but you’ll run the risk of re-tamping some of the grounds and producing an unpalatable shot.
The dishwasher-safe, BPA free model from Takeya can brew up to a quart of concentrated cold brew coffee. It not only yielded one of the best tasting brews, it also aced our usability tests. The brewer is easy to set up, offers a durable build, and is simple to clean and store for later use. It is also the only brewer that is air-tight while it brews, allowing you to easily store the brewer on its side in a packed fridge.

The Baratza Encore is simplicity defined and our top coffee grinder. This burr grinder has a 40-setting grind size selector, an on-off switch for continuous grinding, and a push-button for manual control. That's it. Other grinders include complicated timers, built-in scales, strength adjustment sliders, and other doodads, but Baratza suggests that you don't need them—and they're right. Measure your beans using a separate scale, grind them fresh for each cup. That's the way to do it.
CR’s take: This unassuming, inexpensive Hamilton Beach coffee maker might be easy to miss, but it can brew a mean cup of joe at a fantastic price. In a basic black-plastic finish, it has the essentials—it’s programmable and offers auto-shutoff—and it offers solid brew performance in a decent time frame (10 minutes). Hamilton Beach machines even earned a Very Good rating for predicted reliability. At around $25, this simple model will get the job done.

All the machines we tested came with either insulated carafes or glass pots with built-in warmers. Both have pros and cons. Glass pots are typically easier to clean because they tend to have wider mouths, and the lack of internal insulation means that glass pots will have a greater interior volume relative to its exterior volume — basically, it’s easier to get your hand or dish sponge into a glass pot. On the other hand, glass pots are more fragile and have to be heated from a base plate. In our tests, those base plates could even raise the temperature of the coffee, like with the CuisinArt, which can make coffee taste burnt.
It’s obvious, but easy to forget: If you don’t clean out your coffee machine’s carafe after each use with soap and water, you’ll always end up tasting a little bit of yesterday’s now-bitter brew. Thermal carafes need to be hand-washed, but all the plastic components of our top picks — brew baskets, lids, etc. — are dishwasher-safe if you keep them on the top rack.

Served in a variety of drinks, espressos are made by machines that send pressurized hot water through finely-ground coffee beans—thus, the quality of the drink is dictated in large part by the quality of machine that brews it. Historically, the best espresso has been brewed in coffee shops with industrial-grade equipment. Today, continued innovation in the at-home espresso brewing industry has led to the creation of high-quality machines that can contend with some of the best baristas out there.
It can take a little while to get to know the ins and outs of a new coffee maker. In CR’s labs, each drip coffee maker we test brews roughly 65 cups by the time our engineers are through with it. And brewing is just one of many aspects we look at. We test for handling and convenience, too, so you can choose a model that helps you sail through morning madness.
